Free throws - 1 point
2 - points.
3 - points.
Now,
The different ways to have a score of 24 points without making any free throws.
Case 1:
2 x 12 = 24 points.
Case 2:
3 x 8 = 24 points.
Case 3:
2 x 6 = 12 and 3 x 4 = 12
12 + 12 = 24 points.
Case 4:
2 x 9 = 18 and 3 x 2 = 6
18 + 6 = 24 points
Case 5:
2 x 3 = 6 and 3 x 6 = 18
6 + 18 = 24 points
Similarly, we can have many possible ways.
We have to make sure that the points add to 24 points.

CROSS CONDUCT PROPERTY
By cross multiplication, the result for each pair of rational numbers are listed below:
x = 14 x = 114 / 5 x = 97 / 19 x = 318 / 5 x = 27 / 4 x = 2 x = 109 / 5 x = 94 / 11How to use cross multiplication
Cross multiplication is a property involving multiplication and division between the terms of two rational numbers of the form:
a / b = c / d
Where a, b, c, d are real numbers. Combinations between a numerator and a denominator are multiplications and combinations between two numerators and two denominators are divisions. Now we proceed to solve on each case:
Case 11
4 / x = 2 / 7
4 · 7 = 2 · x
28 = 2 · x
x = 14
Case 12
19 / 10 = x / 12
19 · 12 = 10 · x
228 = 10 · x
x = 114 / 5
Case 13
(x - 1) / 6 = 13 / 19
(x - 1) · 19 = 13 · 6
(x - 1) · 19 = 78
x - 1 = 78 / 19
x = 1 + 78 / 19
x = 97 / 19
Case 14
5 / 17 = 19 / (x + 4)
5 · (x + 4) = 19 · 17
x + 4 = 323 / 5
x = 318 / 5
Case 15
10 / (2 · x - 9) = 20 / 9
10 · 9 = 20 · (2 · x - 9)
90 / 20 = 2 · x - 9
27 / 2 = 2 · x
27 / 4 = x
x = 27 / 4
Case 16
12 / 18 = (3 · x + 4) / 15
2 / 3 = (3 · x + 4) / 15
10 = 3 · x + 4
3 · x = 6
x = 2
Case 17
(x - 20) / 3 = (x - 11) / 18
18 · (x - 20) = 3 · (x - 11)
18 · x - 360 = 3 · x - 33
15 · x = 327
x = 109 / 5
Case 18
6 / (x + 16) = 7 / (3 · x + 3)
6 · (3 · x + 3) = 7 · (x + 16)
18 · x + 18 = 7 · x + 112
11 · x = 94
x = 94 / 11

A forest ranger looking out from a ranger's station can see a forest fire at a 35 degree angle of depression. The ranger's position is 100 feet above the ground. How far is it from the ranger's station to the fire? Round your answer to the nearest tenth of a foot.
To find the distance from the ranger's station to the forest fire, we can use the tangent function and the information given in the problem. The tangent of an angle is defined as the ratio of the opposite side to the adjacent side in a right triangle. In this case, we can use the angle of depression to the forest fire, the height of the ranger's station above the ground, and the distance from the ranger's station to the forest fire to form a right triangle.
We can then use the tangent function to find the distance from the ranger's station to the forest fire as follows:
tan(35°) = opposite/adjacent
opposite = tan(35°) * adjacent
opposite = tan(35°) * 100 feet
opposite = 0.7392 * 100 feet
opposite = 73.92 feet
Therefore, the distance from the ranger's station to the forest fire is approximately 74 feet. To the nearest tenth of a foot, this is 73.9 feet.

Functions are relationships that exist between two variables. Graphing them allows us to observe and predict their behavior. The graph of a function is a line or curve where we can determine random values directly and identify a set of results through it.
The rate of change is one of the calculations we can determine from a graph. It is the change of the function per unit. It is deriving from the slope of the line formed in the interval. The formula for determining the rate of change is:

The values of a and b in the expression x³ + ax³ + bx - 3 are a = 1 and b = -17
How to determine the values of a and b?From the question, we have the following parameters that can be used in our computation:
x^3+ax^3+bx-3
Rewrite properly
So, we have
x³ + ax³ + bx - 3
The expression has a factor of x - 3
This means that
(3)³ + a(3)³ + b(3) - 3 = 0
So, we have
27 + 27a + 3b - 3 = 0
Evaluate the like terms
27a + 3b = -24
Divide by 3
9a + b = -8
The expression has a remainder of 15 when divided by x + 2
This means that
(-2)³ + a(-2)³ + b(-2) - 3 = 15
So, we have
-8 - 8a - 2b - 3 = 15
Evaluate the like terms
-8a - 2b = 26
Divide by -2
4a + b = -13
So, we have
9a + b = -8
4a + b = -13
Subtract the equations
5a = 5
Divide
a = 1
Recall that 4a + b = -13
So, we have

MN = 50
Step-by-step explanation:
You want the length of the base segment MN in triangle MNO, where MN is marked 41+3x and parallel midsegment PQ is marked 49-8x.
MidsegmentThe midsegment is half the length of the parallel base segment. That means the base segment is double the length of the midsegment:
MN = 2·PQ
41 +3x = 2(49 -8x)
41 +3x = 98 -16x
19x = 57 . . . . . . . . add 16x-41
x = 3
MN = 41 +3x = 41 +3·3 = 50
The length of MN is 50 units.
Mary earns $28 000 a year. One week she grossed $658. 0. She had sold $1673. 19 worth of merchandise. What is the rate of her commission?.
Her commission rate is 7.44%.
What is commission rate?
The payment that is either a fixed amount or a percentage of a sale is the commission rate. When they make a sale, people in commission-based professions like insurance brokers, real estate agents, and car salespeople are compensated.
The parameters given are;
The amount Mary earns annually = $28,000
The amount Mary grossed during a week = $658.00
The amount Mary had sold during the week to make the amount grossed during the week = $1673.19
Given that Mary makes $28,000 per year
Therefore;
The amount Mary earns per week = Amount earned per year/52
The amount Mary earns per week = $28,000/52 = $538.46
The amount extra she made on commission = $658.00- $538.46= $119.54
The commission rate = Commission earned/(Amount of merchandise sold)×100
The commission rate = 119.54/1673.19 × 100 = 7.14%

Direct proportion
Two quantities are said to be in direct proportion if on increasing the value of one quantity, the value of other quantity also increases and vice versa.
For example cost of a commodity and quantity of a commodity are in direct proportion
Inverse proportion
Two quantities are said to be in inverse proportion if on increasing the value of one quantity, the value of other quantity decreases and vice versa.

coach jenson bought 15 shirts for $180 for the basketball team. the unit rate for the shorts was 1.50 less than the unit rate for shirts. choach jenson bought the same number of shorts as shirts to complete each uniform. What was the total cost of the uniforms for the team? explain your answer
Answer:
$337.50
Step-by-step explanation:
To find the total cost of the uniforms, you will need to find the unit price of the shirts and the unit price of the shorts and then multiply each by the number of shirts and shorts, respectively.
The unit price of the shirts is the total cost divided by the number of shirts, or $180 / 15 shirts = 12/shirt.
The unit price of the shorts is
$12/shirt - $1.50/shirt = 10.5/shirt.
Since the coach bought the same number of shirts and shorts, the total number of shirts and shorts is 15 shirts + 15 shorts = 30 shirts and shorts.
The total cost of the shirts is $12/shirt * 15 shirts = $12*15 = 180.
The total cost of the shorts is $10.5/shirt * 15 shirts = 157.5
The total cost of the uniforms is the sum of the cost of the shirts and the cost of the shorts, or $180 + 157.5= 337.5.
Therefore, the total cost of the uniforms for the team is $337.5.

what is meant by marginal tax?Marginal tax is the tax rate applied to an individual’s last dollar of income. It is the additional tax that must be paid on any additional income earned. In other words, it is the tax rate that applies to an individual’s income after all deductions. For example, if an individual’s income is $50,000 and the marginal tax rate is 25%, then the individual must pay an additional $12,500 in taxes on top of the $25,000 in taxes already paid on their $50,000 income.
Marginal tax rates are progressive, meaning that as an individual’s income increases, the marginal tax rate will increase as well. The marginal tax rate is important to understand because it helps individuals determine how much additional income they will need to earn in order to make up for the taxes they will have to pay on that income. It is also important to understand how marginal tax rates can affect tax planning strategies.
